you could do something like this:
But the thumb cluster might not be right. That’s the only ergodox style caps that I know of in a profile other than DSA. You could probably get some blanks and do it or fill out a vomit keyset with a grab bag from SP or from Reddit by buying someone else’s grab bag leftovers. Or putting a post up specifically for what you’d need there right after the grab bags sell.
Lastly, the only other option I know of is to get into a GB and grab a set there that has ergodox support. But even then, you might be missing some for your thumb cluster.
